Ha ha on the lansaprazole thing, I'm similar with a med that I'm allergic to. Every time I go to the doctor, they go over my allergies - I'm allergic to a med with the brand name of Compazine, but the generic name of it that's in my file is prochlorperazine and nobody seems to be able to pronounce that.
They're always like, "So you're allergic to, uh.... pro... clora... perz... uh, that?" I'm like, yep, close enough!
